Abstract

PURPOSE: To make the magnitude of thrust load possible to be kept constant, by installing a pressure regulating valve, which works on intermediate pressure in a compression process, in an interconnecting passage interconnecting a pressure chamber installed in the back side of a revolution scroll, to a low pressure chamber.
CONSTITUTION: At the back side of a revolution scroll, there is provided with a pressure chamber 12, while an interconnecting passage 10 interconnecting a pressure chamber 12 to the suction side is installed in a fixed scroll member 2. In an interconnecting passage 17, there is provided with a pressure regulating valve 18, and an intermediate pressure passage 26 serving as a compression chamber 25 to be formed by the revolution scroll 3 and the fixed scroll 2 and opened to the region that becomes intermediate pressure in a compression process is connected to a back pressure chamber 23 of the said valve 18.
